  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics

Piccola depressione tra rocce montonate in un ambiente di bassa quota nei pressi del confine della Valle dAosta con il Piemonte. Non si segnalano disturbi rilevanti. Substrato roccioso a micascisti eclogitici della Zona Sesia-Lanzo.

4.2 Quality and importance

Piccola zona umida interessante per la presenza dellunica stazione valdostana di Tritone punteggiato e di Tritone crestato e di alcune specie vegetali attualmente note in Valle d'Aosta solo per questa località, quali Isolepis setacea (L.) R.Br. e Lythrum portula (L.) D.A. Webb. Di un certo interesse anche le zone rupestri comprese nella riserva naturale.
